Add a -mno-dollar-line-separator command line option to the AVR assembler.
Some frontends, like the gcc Objective-C frontend, emit symbols with $
characters in them. The AVR target code in gas treats $ as a line separator,
so the code doesn?t assemble correctly.
Provide a machine-specific option to disable treating $ as a line separator.
* config/tc-avr.c (enum options): Add option flag.
(struct option): Add option -mno-dollar-line-separator.
(md_parse_option): Adjust treatment of $ when option is present.
* config/tc-avr.h: Use avr_line_separator_chars.
